A physics student performs an experiment with a concave mirror in their physics laboratory. The mirror has a focal length of 20 cm. They place an object 40 cm from the mirror. Using the mirror's Gauss equation, the student must calculate the position of the formed image and the linear magnification of the object. What is the position of the image relative to the mirror and what is the linear magnification of the object?

The image is 60 cm from the mirror, on the opposite side of the incident light, and is half the size of the object.

The image is 20 cm from the mirror, on the same side as the incident light, and is twice the size of the object.

The image is 40 cm from the mirror, on the opposite side of the incident light, and is the same size as the object.

The image is 80 cm from the mirror, on the same side as the incident light, and is the same size as the object.

The image is 40 cm from the mirror, on the opposite side of the incident light, and is twice the size of the object.
